Louis Victor Leborgne ("Tan").

Louis Victor Leborgne was a patient of Paul Broca. "Monsieur Leborgne," as Broca would call him, was also known around in the hospital by the nickname "Tan." His neurologic condition left him with difficulty in speaking, and he could only speak the word "Tan." Leborgne spent nearly half of his entire life in the hospital. He was initially admitted into the psychiatry division of the hospital and was later transferred under the care of Broca toward the end of his life. The story of the Leborgne sits in the crossroads of human thoughts that led to the discovery of cerebral localization. It is the objective of this study to describe the circumstances associated with this patient, which led the great thinkers of that time to discover the language localization in the cerebral cortex. Leborgne's condition was the cornerstone in the evolution of this discovery. More than 150 years have passed since the death of Leborgne, yet Leborgne's brain continues to attract researchers investigating the mysteries of human speech.

Final chapter, From India to the Planet Mars: A Study of a Case of Somnambulism with Glossolalia, by Théodore Flournoy (1900).

Among the many attempts to explain mediumship psychologically at the turn of the century were the efforts of Swiss psychologist Théodore Flournoy (1854-1920). In his well-known book Des Indes à la Planète Mars (1900), translated as From India to the Planet Mars (1900), Flournoy analysed the mediumistic productions of medium Hélène Smith (1861-1929), consisting of accounts of previous lives in France and in India, and material about planet Mars. Flournoy explained the phenomena as a function of cryptomnesia, suggestive influences, and subconscious creativity, analyses that influenced both psychology and psychical research. The purpose of this Classic Text is to reprint the conclusion of Flournoy's study, whose ideas were developed in the context of psychological attention to mediumship and secondary personalities.

1910s' brains revisited. Cortical complexity in early 20th century patients with intellectual disability or with dementia praecox.

OBJECTIVE: The idea of cortical surface anomalies in subjects with intellectual disability (mental retardation) and schizophrenia can be traced back to early 20th century qualitative observations. Since it is unknown whether modern quantitative measures of cortical complexity and folding would retrieve those early empirical observations, we measured fractal dimension and sulcal span index in photographs of human brains taken in the 1910's. METHOD: Brain photographs were compared between 36 patients with mental retardation and 21 patients with dementia praecox for the fractal dimension and sulcal span index. Also, a mental retardation subgroup with no-or-non-understandable speech (n = 12) was compared with a subgroup with comprehensible speech (n = 23). RESULTS: Mental retardation group had a lower whole-brain fractal dimension than dementia praecox, and a higher sulcal span index in left posterior cortex. The mental retardation subgroup with comprehensible speech had a lower fractal dimension in left hemisphere than the subgroup with no-or-non-understandable speech and a lower sulcal index in left posterior cortex. CONCLUSION: Measures of cortical complexity and folding suggest differences between mental retardation and dementia praecox, and regional variations according to language abilities in mental retardation. The findings provide a unique picture of cortical surface changes in their original untreated form, one century ago.

Ginevra de Benci's portrait: had the lady a myopathic face?

The portrait of Ginevra de Benci was painted by Leonardo da Vinci around 1474. This painting is less famous and less known than Mona Lisa but it is extremely captivating and interesting due to its own characteristics. The overall picture gives to the viewer the impression of being in front of an enigmatic, hermetic and introspective woman. However, some details of her facial expression, especially the gaze direction, the upper eyelids' heaviness, the flat mouth and the absence of any defined emotion, give her the appearance of a patient with a muscular disease.

The 'idioglossia' cases of the 1890s and the clinical investigation and treatment of developmental language impairment.

The early history of developmental language impairment in late 19th century Britain is considered through the critical examination of three papers appearing in 1891 by Hadden, Golding-Bird and Hale White, and Taylor. They represent innovative investigations of child language disorders whose themes and concerns are resonant today. The term 'idioglossia' was coined to identify this new impairment and reflected the belief by some that these children spoke an invented language. Rather than viewing these children as having some constitutional deficiency, these 19th century physicians were novel in insisting that children with language impairments merited extensive clinical investigation and treatment. Their case descriptions and the subsequent debates regarding classification and prognosis are reviewed. Further consideration is given to how these cases led to questioning the relation between language and speech and other aspects of child development and disorder. Reflection on the early sources of clinical categories provides a new perspective on our current formulations for variation in developmental language trajectories.

Transcribing speech: practicalities, philosophies and prophesies.

This article outlines the main practical and philosophical developments which have contributed to current approaches to phonetic transcription. Particular contributions from scholars in the field are highlighted as seminal in shaping transcription work. Consideration is also given to the ways in which insights from clinical transcription impact upon the analysis of non-clinical data. Finally, the trends which look set to emerge in future transcription practice and research are speculated upon.

Alexia and agraphia: contrasting perspectives of J.-M. Charcot and J. Hughlings Jackson.

OBJECTIVE: To evaluate 19th-century concepts of cerebral localization for complex mental activities, focusing on alexia and agraphia in published writings of Jean-Martin Charcot (1825-1893) and John Hughlings Jackson (1835-1911). BACKGROUND: In the early 1860 s, Broca's reports on a special role for the left frontal lobe in articulate language ignited frenetic interest in cerebral localization. Disorders of written language (alexia and agraphia) were enmeshed in ensuing discussions of how the brain was organized for language and other complex behaviors. DESIGN/METHODS: Focused review and analysis of Charcot's and Hughlings Jackson's publications on aphasia, alexia, and agraphia. RESULTS: In the wake of Broca's observations, the extent to which language functions in general--or such specialized functions as reading and writing--might involve focal cerebral representation was controversial. Based on his clinical-pathologic approach to "regional diagnosis," Charcot came to value insights provided by "partial isolated aphasias." He described patients with isolated alexia and agraphia, and he proposed a functional-anatomic framework to accommodate these disorders. Adopting a hierarchical model of nervous system organization, Hughlings Jackson argued that reading and writing could not be dissociated from other aspects of "intellectual language." Charcot's reductionism was typical of his era, but Hughlings Jackson's more holistic approach was to gain ascendancy in early decades of the 20th century. CONCLUSIONS: Charcot's and Hughlings Jackson's positions on alexia and agraphia reflected contrasting philosophical approaches to the study of brain disorders. Their views informed the opinions of their contemporaries and neurologic heirs in important debates on cerebral organization.

David Livingstone's uvulectomy.

In April 1852 in Cape Town, South Africa, Dr David Livingstone, then 39 years of age and yet to commence the explorations of Africa which would bring him to public attention, underwent the surgical procedure of uvulectomy. This article reviews the history of Livingstone's uvulectomy and its indications and outcome, as documented by his own writings. The practice of uvulectomy in indigenous African societies and some contemporary ideas about uvulectomy are also considered in order to try to ascertain why Livingstone elected to undergo this procedure.

'Study of several involuntary functions of the apparatus of movement, gripping, and voice' by Jean-Marc Gaspard Itard (1825).

Itard's 1825 paper, written while he was Chief Physician at the National Institute for Deaf-Mutes in Paris, demonstrates his empiricist approach to medicine. That is, Itard founded his medical practice on sense and experience rather than on surgery and medication. If all knowledge came through the senses, Itard reasoned, those lacking knowledge or social abilities could be improved by appropriate sensory stimulation. This concern with senses and society, along with his different approaches to men and women, his references to contemporary cures and his comparisons between humans and animals, document early nineteenth-century medical and psychological attitudes and treatments. Itard's paper also contains what was later recognized as the first clinical observation of Gilles de la Tourette Syndrome (TS).

Premature thoughts on writing disorders.

Three papers appeared in the 19th century describing the dissociation between speech and writing: Marce (1856), Ogle (1867), and Pitres (1884). An account of the convincing evidence of dissociations put forward in these papers is presented. Three explanations are proposed as to the reason why the observations reported by these authors were overlooked or rejected by their contemporaries, namely: (a) in the first half of the century it seems that very little knowledge of the processes underlying writing (as opposed to speech) was available, (b) the debates focussed on the independence of speech versus motor control and language versus the intellect, (c) parallelisms between phylogeny, ontogeny and aphasia impeded the application of the principle of double dissociations, including the dissociations between speech and writing. It is argued that this phenomenon in the history of aphasia is best captured by the concept of prematurity in scientific discovery proposed by Stent (1972, 2003).
